  • Publication number: 20240135873
    Abstract: A display substrate and a display device are provided. The display substrate includes a base substrate and a plurality of reset signal lines. The base substrate includes a display region which includes sub-pixels arranged in array, each sub-pixels includes a pixel driving circuit and a light-emitting element. The plurality of reset signal lines extends in a first direction and include a plurality of first reset signal lines for providing a first reset signal and a plurality of second reset signal lines for providing a second reset signal, and one of the plurality of first reset signal lines and one of the plurality of second reset signal lines are respectively connected to pixel driving circuits of a plurality of sub-pixels located in a same row. A layer where the plurality of first reset signal lines are located is different from layers where the plurality of second reset signal lines are located.

  • Patent number: 11913128
    Abstract: A method for compact and flat bismuth metal preparation by electrolysis is provided. In the method, one or more of ?-naphthol, acacia, sulfonated and vulcanized alkylphenol ethoxylate and naphthol ethoxylate oxides are added to the acidic solution of bismuth methanesulfonate as additives, and the cathodic bismuth is obtained by electrolysis at 20-80° C. The method for bismuth metal preparation is simple and easy to promote, environment-friendly, and the obtained bismuth metal has a flat and compact surface and good plate formation effect.

  • Publication number: 20210165479
    Abstract: A method for controlling switching of proximity-event detection elements, a terminal device, and a non-transitory computer readable storage medium are provided. The method includes the following. An instruction of switching a screen of a terminal device from a current first state to a second state is obtained. A first element is switched from an activated state to a non-activated state and a second element is switched from the non-activated state to the activated state by invoking a pre-established switching thread when the instruction of switching the screen from the first state to the second state is obtained. The screen of the terminal device is switched from the first state to the second state when a switching success notification is obtained from the switching thread.
